"We obviously didn't support Mr. Trump in the election," Trumka said at a recent gala. "We endorsed and actively supported his opponent."

He said that after Trump won, his union reached out to Trump - and vice-versa - to see how they could work together even though Hillary Clinton lost.

"We'll judge you by what you do," Trumka said of the initial dealings. "You do good things and we will support them. You do bad things and we will oppose you."

He said the Trump White House essentially reneged on its offer to advocate for laborers and union workers by attacking health and safety standards for miners.

Trumka added that he was troubled by the dual issue of the globalist faction in the White House overtaking the anti-globalists, and that those that did advocate for workers' rights had untoward opinions on race.

"You had two factions in the White House. You had one faction that actually had some of the policies that we would have supported on trade and infrastructure, but they turned out to be racist," Trumka said.

"On the other hand, you had people who weren't racist, but they were Wall Streeters. And the Wall Streeters began to dominate the administration and has moved his agenda back to everything that I think they fought against in the election."

Trumka said that, after neo-Nazi factions rioted in Charlottesville, Va., Trump "made what I considered a terrible statement."

"There were two issues - Symbolism of being connected with him, with that type of statement. [It] was a spirited defense of white nationalists, neo-Nazis and other groups."
